Programmable USB Type-C and Power Delivery 3.1 Source Controller with PPS Support

The FUSB15101 is a highly integrated USB Power Delivery (PD) power source controller that can control the opto−coupler in the secondary side of an AC−DC adapter or a DC−DC port power regulator. The FUSB15101 enables a complete solution for USB power sources through optimized hardware peripherals and complete open−source embedded firmware all in a compact solution. It integrates a highly efficient Arm® Cortex®−M0+ processor with custom designed peripherals to seamlessly support USB PD 3.1 source applications. The FUSB15101 supports the PPS specification in USB PD, with a minimum of 3.3 V and a maximum of 21 V output voltage control. It includes Constant Voltage (CV) and Constant Current Limit (CL) control blocks, various protection mechanisms and high voltage tolerance on connector pins.
